Preheat your oven to 375°F (190°C).
Cook the chickpea macaroni in boiling water for 2 minutes less than the package directions suggest, then drain and set aside.
Dice the chicken breast into bite-sized pieces.
Heat the olive oil in a skillet over medium heat and sauté the chicken until cooked through and lightly browned.
Season the chicken with garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Steam the chopped broccoli florets for 3-4 minutes until they are just tender.
In a small mixing bowl, whisk together the Greek yogurt, chicken broth, nutritional yeast, and half of the shredded cheddar cheese.
Combine the cooked pasta, seasoned chicken, and steamed broccoli in a bowl, then pour the cheese sauce over them and toss until well coated.
Transfer the mixture into a small oven-safe baking dish and sprinkle the remaining cheddar cheese over the top.
Bake for 10-12 minutes until the cheese is melted and the edges are bubbling.
